Introduction

In this blog we will see how to delete list of items from database using entity framework.

Step 1: Create asp.net web application

WebForm1.aspx

  1. <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="DeleteList_EntityFramework.WebForm1" %>
  3. <!DOCTYPE html>
  5. <html xmlns="http://www.w3.org/1999/xhtml">
  6. <head runat="server">
  7. <title></title>
  8. </head>
  9. <body>
  10. <form id="form1" runat="server">
  11. <div>
  12. <asp:Button ID="Button1" runat="server" Text="Delete Data" OnClick="Button1_Click" />
  13. </div>
  14. </form>
  15. </body>
  16. </html>

WebForm1.aspx.cs

  1. using System;
  2. using System.Collections.Generic;
  3. using System.Linq;
  4. using System.Web;
  5. using System.Web.UI;
  6. using System.Web.UI.WebControls;
  8. namespace DeleteList_EntityFramework
  9. {
  10. public partial class WebForm1 : System.Web.UI.Page
  11. {
  12. protected void Page_Load(object sender, EventArgs e)
  13. {
  15. }
  17. protected void Button1_Click(object sender, EventArgs e)
  18. {
  19. EmployeeDBEntities context = new EmployeeDBEntities();
  20. List<Employee> employees = new List<Employee>()
  21. {
  22. new Employee{EmpId=1},
  23. new Employee{EmpId=2},
  24. new Employee{EmpId=3}
  25. };
  27. foreach (Employee employee in employees)
  28. {
  29. context.Employees.Remove(employee);
  30. }
  32. context.SaveChanges();
  33. }
  34. }
  35. }

Output of the application looks like this
